  • The entire process of the quiescent projectile accelerated by high-pressure gas to shoot out at a supersonic speed and fly out of the range of precursor flow field was simulated numerically.The calculation method was based on arbitrary Lagrangian-Eulerian equations and second-order precision Roe method by adopting the chimera grids,dynamic mesh and immersed boundary method.From the predicted results,the coupling and interaction process among the precursor flow field,propellant gas flow field and the high-speed projectile were discussed in detail.
